The invention `has relation tor an attachment assembly unit for liquid coolers operating by mechanical refrigeration and of which there are quite a number Qn'the market offdiferent'makesq :5 an object being to provide vsuch an assembly unit comprising a cup* dispenser, a liquid measuring dispenser and anoperating device or means of simultaneous operati-on for thev cup dispenser and vthe 'liquid' dispenserl all'l located forwardly of the I0 face of the cooler in transverse alignment and' in full' view, the cupssuccessively released from the cupY dispenser falling upon the cup rest which is part of; the cooler and the liquid measured-.and

dispensed being discharged into the cup juponY saidy rest. Another object is to` provide the cup dispenser, the liquidY dispenser and the operating device stated all mounted on a vertical face plate attachable closely to the face of the cooler. Another object is to provide such; an assembly unit adapted' for attachment to different makes of Vcoolers byl an unskilled person in a short time. Another object. is to provide such an assembly unitv the members of which Yare, all located in'full View and readily accessibley for inspection, re,- pairs, disconnection, replacement, etc.` Another object is to provide such an assembly" unit' constructed so that the operatingA means `for the cup release and the liquid4 dispenser may take Mplace by' a'fractional turn ofthe operating'shaft in one direction, the reverse turn ofthe operating shaft serving to return the. partsv to normal position. Other objects and advantages will appear herein,- after.

The invention consists in the novel construction and combinations of parts as set forth in the appended claims.

In the accompanying drawing illustrating an embodiment of the invention- Figure 1 is a front view of the invention, partly 46 broken away.

Figure 2 is a'plan'view with parts in section. Figure 3 is a detail section on the line 3 3,

Figure l.

Figure 4 is a detail section on Figure 1.

`In the drawing, the numeral l designates the vertical attachment plate, which is bolted or screwed to the front face of the cooler 2, said plate extending upwardly in front of the liquid reservoir 3 of the cooler. and being located close to the front face of the cooler, the cup rest being shown 'Ihe cup dispenser the details of which are no part of the present invention and which are well the une 444,

`dispenser is located above the cup rest 4 and the 'valve casing thereof has a lowervdischarge spout known is shown at 5, operation of the lever 6 of K said dispenser successively releasing cupsone ata time which thereupon -fall upon theV cup rest af'or'esaid, a deilector "I- secured to the plate 1 serving to direct the cup into thebase holder -8 of said rest so that it will fall in upright position. Y This cup dispenser is secured to the' plate'l at one side thereof andl close thereto. I v

The liquid measuring dispenser is Y'shown at`9, and comprises av measuring vessel having a lower orice ylycommunicating with vthe upper orifice 11 of a valve casing 12, wherein works a three way valve 13, a rear orifice 14 of said valve 'casing having astub pipe 15 extending rearwardlyacross the-plate 1 andV threaded at 16 so that it may be readily Vcoupled to the discharge pipe 17 of the 70" reservoir 3 of the cooler. This liquid measuring dispenser islocated centrally'of the plate l and of the cooler and spaced from the cup dispenser in transverse, alignment therewith. vThis liquid V19 delivering the` measured contents of the "dispenser into the cup upon said rest. Y'

The ,means of vsimultaneous operation of the cup dispenser and of the valve of the liquid measuring dispenser, comprise a casing 20, which is ,Y secured to the attachment plate l close thereto, ai rotary operatingshaft 21 having bearings in said casing and being provided with a forward `handle 22, said shaft having` a rear gear wheel 23 meshing with a vertical rack 24,' the lower portion of said raclr meshing withanother gear wheel 25,( fast to a lateral stub shaft 26, having bearingsy in said casing and beingV in lineY with '90 ay lateral stub shait-27 Vof the three way valve 13 of the'liquid dispenser, these two shafts 26 and 27 having a clutch connection 28 which is readily engaged and disengaged by movement of stub shaft 26, which has sliding bearings in said casing, the gear wheel 25 moving therewith and placing a spring 28 under tension, said spring restoring the clutch connection upon release of the shaft.

Upon operation of the shaft 21 one quarter turn to the right, the three way valve 13 will be similarly operated to establish communication between the discharge pipe 17 vof the liquid reservoir andthe measuring vessel 9, whereupon liquid will flow into said vessel to an extent determined by the height of the vent pipe 29 of said vesseLsaid vent pipe being slidably adjustable for height to vary the charge of liquid in said vessel. That is to say when the liquid so discharged rises to cover the lower end of the vent pipe, the discharge of liquid will stop for obvious reasons.

The operating shaft being when given a one y quarter reverse turn to normal position, the three way valve will be similarly operated to establish communication between the measuring vessel and the discharge spout thereof to deliver the liquid so measured into the cup located upon the cup rest.

In order that the cup dispenser may be operated simultaneously with the liquid dispenser to release the cup so that the latter will fall into position on the cup rest ready to receive the liquid discharged from the measuring vessel as stated, said operating shaft is provided forwardly thereof with an eccentric 30, and the cup dispenser casing is provided forwardly thereof with a lever 31, a connecting rod 32 being operated by said eccentric or crank 30 and in turn actuating the lever 31 to push the latter forwardly upon its fulcrurn 33, said lever having a pivotal link connection 34 with the lever 6 of the cup dispenser to release the cup during the quarter turn forward of the operating shaft. The connecting rod 32 extends horizontallyvand transversely in front of the measuring vessel 9, said rod having in the present instance an upwardly and inwardly bent end 35, engaging a perforation of the eccentric 30 and at the other end being bent downwardly at 36 to engage aperforation of the lever 31.
